That's not quite what I was asking. I generally believe that Facebook ads can be successful. I'm curious about what companies are effectively using them now at a large scale.

I also suspect that the effectiveness of Facebook ads has a lot to do with the nature of the product/service being advertised, and the ad itself (just like any advertising).

Your comment applies your specific experience (unknown to me) as evidence for an absurdly general statement ("Facebook ads are worth it") and an ad hominem attack on the author of the article. Classy.
